Your PHP is probably too old. To find out Apache versions, run the apache binary with -v or -V (for compile options); alternatively, unless you've told Apache not to talk about its version, you can just request an inexistent page (yourserver/inexistent.html) and read the standard footer. If neither works - for instance, if the server is not yours - you can telnet to port 80 and issue a HEAD directly; this'll work unless version hiding was explicitly turned on in httpd.conf.
